PHEOC

Problem

• Does the current impact the chemicals found in the Pewaukee River?

Hypothesis

• I think the current has an impact on the chemicals found in the river because last year we learned that if the river is not flowing at all of just a little bit the river is probably not that healthy and if it's not healthy there might be bad chemicals in it that cause allege and possible killing of fish and plants by or in the river.

Experiment

• Materials Used
  • River Water
  • Test Tubes
  • Chemplate
  • Chemical liquid solution
  • Chemical solid solution
  • Laptop camera
  • Little Spatula
• Procedures
  • Take the amount of water that the instructions say from the river into a chemplate or test tube
  • Put chemical liquid or solid solution into the tube or chemplate
  • Then mix if the directions say so
  • If the water turns to a certain color, the chemical is in the river
  • These are the steps of most of the directions for the different chemicals
• Variables
  • Constant
    • The tubes and the chemplates
  • Independent
    • I changed where we were testing for the chemicals
  • Dependent
    Therefore the chemicals were in different places in the water

Observation

pH Levels	Copper	Nitrates	Iron	Phosphorus
Yes	Yes	Yes	yes	yes
Silica	Sulfide	Chromium	Cyanide	Ammonia Nitrogen
Yes	yes	yes	yes	Yes

Conclusion

• We went down to the river and we tested the water for chemicals by using a chemical testing kit. The kit included test tubes, chemplates, chemical testing solution, and a little spatula to stir things. The hypothesis was not supported. I tested water that wasn't moving that much and no one tested water that was moving a lot.

I don't think the water is clean. I think this because almost every chemical we tested was in the river and they are all dangerous to fish and/or plants.
